TommyGirl226, Some questions: Any thing you can think of that happened in the last 2 months to make his condition worse? Changes in the household? --- of people (stress thro job loss, relationship issues), addition/deletion of other pets? furniture changes? different household products? In past couple months, our windows have been closed more--perhaps more toxins, allergens concentrated? Our furnaces have been on, so air is drier...did you try a humidifier?
